Tinmendo is an interactive music app for Android and iOS that we created for the innovative music group Tin Men and the Telephone. It allows the audience to actively participate in their live performances. The audience influences the show by swiping, texting and shaking their new smartphone instrument and are invited to create beats, melodies and harmonies that are performed by the band on the spot. During each performance, a brand new composition is created that is interactive, improvised and unique to that particular time and place!
